  • 1 teaspoon oil
  • 3 cloves garlic minced
  • salt to taste
  • pepper to taste
  • 2 ½ cups low-sodium chicken broth or vegetable broth
  • 1 cup milk skim or 1%
  • 3 teaspoons cornstarch
  • ½ teaspoon onion powder
  • ½ teaspoon dried basil
  • 1 teaspoon dried parsley flakes
  • 1 cup freshly grated parmesan cheese

Instructions

  • Turn the Instant Pot to the sauté setting. Add 1 teaspoon of oil and heat briefly.
  • Add the minced garlic and sauté for about 30 seconds or until fragrant, careful not to burn.
  • Add the broken fettuccine noodles directly into the pot.
  • Pour in 2 ½ cups of low-sodium chicken or vegetable broth, ensuring noodles are submerged.
  • Sprinkle in salt, pepper, onion powder, dried basil, and dried parsley flakes. Stir gently to combine.
  • Secure the lid, set steam release valve to sealing, cook on high pressure for 5 minutes.
  • Allow pressure to release naturally for 5 minutes, then quick release remaining pressure.
  • Remove lid and stir cooked fettuccine.
  • Whisk together milk and cornstarch in a small bowl until smooth. Pour into the pot and stir to thicken sauce.
  • Stir in freshly grated parmesan cheese until melted and creamy. Adjust seasoning with salt and pepper as needed.
  • Spoon into bowls, garnish with extra parsley or cheese if desired, and serve hot.

Equipment

  • Instant Pot
  • Measuring Cups and Spoons
  • Wooden spoon or spatula
  • Grater

Notes

  • For a dairy-free version, substitute milk with almond or oat milk and use nutritional yeast instead of parmesan.
  • You can swap fettuccine with whole wheat or gluten-free pasta, adjusting cooking times accordingly.
  • Leftovers can be stored in an airtight container in the fridge for up to 3 days; reheat with a splash of milk or broth to loosen sauce.
